if people only bothered to think about things that exist (especially things that they think exist) we would probably go the way of the dodo. funnily enough that would prevent the dodos from going that way but whatever.

I highly recommend watching the Vsauce video on supertasks—it's a great video as expected from Vsauce but also ends on a great note about people and their tendency to think about things like this.

There are some pretty close physical analogs that are fun to think about. You cant move a black hole by exerting physical force on it in the normal way so practically infinite gravity wells are like a immovable "object", though if you're sufficently nerdy enough you can cook some fun ways to harness its gravitational rotation into a kind of engine, or throw another black hole at it to create a big explosion and some gravitational waves which are like a kind of unstoppable force moving at the speed of light.

You clearly haven't met my mother.

Neutrinos are pretty close to an unstoppable force: they can pass right through the earth without being stopped.

I believe this is an expectation of dark matter, to being even closer to an unstoppable force. Perhaps a reason we haven’t found it yet would a because we don’t have a detector that can stop it

These kinds of contradicitons exist in man made structures, such as laws, rules and regulations. In situations like that, a judge has to pick which rule to follow and which one to ignore. The first time that happens, it becomes the standard solution (precedent) for those kinds of problems.

"And irresistible is what I am, baby!"

That's on the nsfw version of xkcd

A rock so heavy you cannot lift it is not an immovable object. Just cause you are weak does not mean you are right.

I think if God creates a rock so heavy he can't lift it, it's probably a black hole. By definition we can't know what happens inside a black hole, because no information escapes the event horizon. As it's now consistent with known physics that we can't know many aspects of this interaction between God and the black hole, I think this paradox is basically solved. We don't know any more about the interaction, but it's no longer a paradox, it's consistent with physics.

They met, they just didn’t interact. Kinda like me at a work party.
